MACHINE FOR SEWING FILLED sAcKs.

SPECIFICATION forming part of Letters Patent No. 607,81 1, dated July 19, 1898.

Application filed August 30, 1897- 'Serial No. 649,936. tub model.) I

To all whom it may concern.-

Be it known that I, ARTHUR T. TIMEWELL, a citizen of the United States, residing in Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Machines for Sewing Filled Sacks, of which the following is a specification.

This invention relates to'improvements in machines for sewing filled sacks, and has been devised more especially for use in connection with the machine shown in my application, Serial No. 646,608, filed July 31, 1897. In the machine described in my'said application the filled sacks or bags are fed into the bite of two opposing endless chains or belts moving in the same direction and adapted to convey the sack orbag past suitable sewing mechanism, whereby the edges at the mouth of the sack or bag are sewed together, the chains or belts being held in close contact, so they will retain a firm grip upon the sack or bag by means of pulleys or sprocket-wheels, and suitable guides between the pulleys or sprocketwheels. In the sacks or bags sewed in said machine the edges of the cloth are left projecting and exposed and present an unfinished appearance. My effort in this invention has been to combine with the feeding chains or belts of the sewing-machine a guide upon which the raw edges of the material of the bag or sack may be turned or folded down before the bag is fed into the grip carrying chains or belts, so that the sack or bag will be presented to the sewing mechanism while thus folded and sewed both through the folded and the unfolded portion of its mouth. By the use of this improvement the raw edges of the cloth are positioned where they will be practically unnoticed and the security of the closure is much increased.

In the accompanying drawings, forming a part of this specification, I show at Figure l a side elevation of a filled-sack-sewing machine provided with myim provement, at Fig. 2 a partial plan of the same machine, and at Fig. 3 a vertical section of the bag and folding-guide.

. In said drawings, A A represent the opposing feeding-chains between which the bag is gripped and'fed.

B B are the wheels around which the chain passes at each end of the path through which the bag is gripped, the wheels at one endbeing driven by a power from the main shaft O through the gears D and E and the'diagonal shaft F. The table of the machine G is slotted along the line traversed by the bag and the bags X are supported while passing through the machine either by the chains or by a carrier II, located below the table. This carrier may also be driven, as plainly indicated in Fig. l. The needle-bar of the sewing mechanism is indicated at J and is located so as to carry the needle through the bags along a plane immediately under and parallel to the chains A. The bag marked X in Fig. 1 has been sewed, as indicated by the line of stitches Q3.

The details of this sewing-machine are not given here, as they are fully explained in my said prior application; but the present invention can be used with any filled-sacksewing machine having means for gripping the edges at the mouth of the bag and presenting them to the sewing-machine while thus gripped.

The novel feature of the present improvement is found in the guide-bar L, located in front of the point at which the bags are fed to the gripping and feeding devices of the machine and supported in any suitable wayas, for instance, by the bracket M, attached to the frame of the machine. The flat sides of this bar are vertical and its top edge is positioned in substantially the same plane as the top of the gripping-chains. When the bag reaches this bar, the operator turns the edges of its mouth down over the bar, as indicated at Fig. 3, and retains control of the folded edges until the bag has been passed into the grip of the chains, the guide-bar being preferably extended into close proximity to the chains at the receiving-point, as plainly indicated at Fig. 2. The fold will now be held by the chains and the stitching will take place through both the folded and the unfolded parts of the mouth of the bagin other words so the mouth of the bag will be stitched twice, once through the folded-over edges and once through the unfolded portion back of the fold. This operation requires no time upon the part of the operator and does not delay the operation of the sewing-machine, and consequently the machine maybe worked to its full capacity in this way.

I claim 1. The combination in a filled-sack-sewing machine, of opposing traveling gripping and feeding devices for laterally gripping the mouth of the bag and feeding it to the sewing mechanism, and a guide over which the mouth of the bag may be folded and presented to the gripping and feeding devices in position to insure stitching through both the folded and the unfolded part of the mouth, substantially as specified.

2. The combination in a filled-sack-sewing machine, of sewing mechanism, a carrier for the filled sacks, a bar or guide over which the mouths of the sacks may be folded, and opposing traveling sack-mouth gripping and feeding mechanism for laterally gripping feeding and conveying the folded mouth of the sack from the bar to the sewing mechanism, substantially as specified.

The combination in a filled-sack-sewing machine, of sewing mechanism, a carrier for the filled sacks, a bar or guide over which the mouths of the sacks may be folded, and opposing traveling endless gripping and feeding mechanismfor laterally gripping feeding and conveying the folded mouth of the sack from the bar to the sewing mechanism, substantially as specified.
